Resumo

3D printers are small and affordable machines which allow, from a numerical drawing, the direct realisation of an object. In common printers, a plastic filament, available in spools, is melted and extruded, and then solidifies to form the object. In order to understand the very interest of such machines in the frame of mechanical engineering teaching, we have to recall a concept introduced in the 80´s and fully applied today: the CAD/CAM concept. CAD/CAM stands for Computer Aided Design / Computer Aided Manufacturing that is to say an integrated numerical chain from design to manufacturing. As CAD/CAM software are now able to run on standard computers, we took this opportunity to create, in 2015, a pole of competency at the Laboratory of Vibrations concerned by the design and calculation of mechanical parts. The manufacturing itself, which is generally handled by CNC (computer numerical control) industrial machines, was not part of the initial project. However, in 2017, we decided to acquire a 3D printer as an educational substitute to CNC. From that time, the interest of the students renew, not less than 6 projects were carried out, fairing of mini-rocket, wind-turbine blade, parts of an off-road car, educational samples... Be the power of reality nor another factor, this interest of the students for concrete realisation should be underlined and certainly should deserve to be studied moreover.
